The geochemical studies of stable isotopes on iron and nickel

Abstract

In recent years, variation in the relative isotopic abundances have been studied in many elements. It is important to study for the origin of elements and also for the isotopic geochemical study. Iron and Nickel might be suitable for such an investigation because they are predominant elements in cosmos and they occurs in terrestrial materials formed under very different conditions. The relative isotope ratios of iron and nickel were studied in four meteorites and a few terrestrial samples. I have likewise observed no significant difference within the experimental error.
